10 Claims.

The object of the instant invention resides in providing an electric bread toaster constructed as hereinafter set forth and having the functions and advantages recited.

The bread toaster disclosed in this application consists of a case A in which is disposed a framework B. 'Ihe framework B andassociated parts provides two vertical bread ovens C into which the bread may be placed through suitable openings in the upper portion of the case A. Within the framework B is disposed two vertically movable bread racks D which support the bread within the ovens C and which are spring biased to nontoasting position. A timing mechanism E is adapted to determine the cooking period and operates to release a latching device F whereupon the bread racks are returned to normal position at the end of the cooking period. The timing mechanism includes a revoluble member having catch engaging means adapted to be engaged by a catch movable with the bread racks and forming part of the release F. The catch engaging means has a surface disposed transversely of the direction of movement of the catch, the angularity of which changes as the member rotates to cause said surface to approach parallelism with the direction of movement of the catch. Due to the change in angularity of the surface of the catch engaging means the friction between the catch and catch engaging means is greatly reduced at the point of release thereby making release positive and requiring only a small amount of energy.

In the drawings:

Fig. 1 is a plan view of a portion of an electric toaster illustrating an embodiment of my invention with portions broken away to illustrate the construction thereof.

Fig. 2 is a longitudinal elevational sectional view of the toaster taken substantially on line 2-2 of Fig. 1.

Fig. 3 is a fragmentary cross sectional view taken substantially on line 3-3 of Fig. 1.

Fig. 4 is a fragmentary cross sectional view taken substantially on line 4-4 of Fig. 1.

Figs. 5, 6 and 7 are views similar to Fig. 4 showing the parts in altered positions.

The case A of my invention as best shown in ,1T-ig. 2 consists of a lower case section I0 which ,extends about the entire toaster and which has ends II and sides I2. The lowermost part of the case section I has a flange I3 extending inwardly therefrom and on which the toaster mechanism rests. The upper part of the section I0 has an offset I4 formed in the same and which provides a recess Il. Overlying the section l0 is an upper case section I5. This case section is dome-shaped in form and the lower marginal portion I5 of said case section is received within the recess Il formed by the oifset I4. Screws I8 extending through the lowermost marginal portion I6 and threaded into the offset I4 hold the parts of the case assembled. Attached to the ends II of case section I2 are end pieces I9 which are preferably constructed of some plastic material and which form ornaments for dressing up the case structure. These end pieces have body portions 2I which overlie the ends II of the case and are secured thereto by means of screws 22. These end pieces furthermore have feet 23 which are disposed beneath the section I0 and support the entire toaster above the table on which it rests to provide ventilation and retard the transfer of heat to the table. AThe section I5 of the case A is constructed with openings |44 which register with the bread ovens C and through which the bread may be inserted into said ovens and placed upon the bread racks D.

Within the case A is located the framework B which supports the mechanism of the invention. This framework consists of frame 24, of inverted U-shaped form, having an upper longitudinally extending frame member 25 and two vertically extending frame members 26 and 2l connected thereto. The frame members 26 and 2l have anges 28 projecting outwardly therefrom and lying in a, common plane. These flanges rest upon the iiange I3 and support the frame structure through the lower case section I0. Screws 20 hold the framework B attached to the case A.

Within the framework B is provided four heating elements 29, 3I, 32 and 33 which consists of sheets of mica 34 on which are wound suitable resistors 35. These heating elements in conjunction with the vertical frame members 26 and 2l, form the two bread ovens C which are disposed between the heating elements 29 and 3l and between the heating elements 32 and 33. The heating elements 3l and 32 are also separated from one another to form a space 36 therebetween and in which certain of the mechanism of the invention is disposed. For supporting the heating elements 29, 3 I, 32 and 33 two bars 31 are employed which extend transversely of the frame members 26 and 21 and are attached thereto by means of screws 38. The said screws are insulated from the frame by insulating washers 39. Other screws 4I extend through said bars and through angle brackets 42 secured to the various heating elements by means of rivets 43. The

heating elements 29, 3|, 32 and 33 have reinforcing strips 44 secured to the upper and lower ends of the same and which also serve for attachment of guide wires 45. These guide wires are spaced from the resisto-rs and prevent the toast from coming in direct contact therewith and burning.

For supporting the toast within the oven C the two bread racks D are employed. These bread racks consist of elongated bars 46 which extend through slots 41 in the vertical frame members 26 and 21 and are guided for vertical movement therein. One end of each of said bars has an arm 48 bent outwardly therefrom and which terminates in a lug 49. The lugs 49 straddle two levers 52 and 53 and arepivotally connected thereto by means of rivets 55.

The lever 52 is pivoted to anjupright 55 by means of a rivet 62. This upright is secured to the frame B in the following manner: The upper end of said upright has a nger 56 which extends over the horizontal frame Ymember 25 and is formed with a lug v51 which projects downwardly through said'frame member. The lower .end 'of the upright has a iiange`v 58'projecting outwardly therefrom which is secured'by means of a rivet 59 to 'the flange' 28 of frame 24. Another lever l'hereinafter'referred tov as a rack vlever isfalso pivotedto theupright`55 by means tween the'lever 52 and the lever 6| is abell crank 66 which has one long `.arm 61v pivoted to the ylever 6| by means of a screw 68. VThe said lever vhas a short arm 69 which is'pivoted to the lever 52 by means of a screwV 1|. Lever 53 is pivoted to the bell crank 66 by means of-a rivet 12.

Below the lever'rl is another lever 13. `This lever extends completely'through the frame 24 and'its innermost endis formed' with an upstanding arm 14. Thisfarm is'pivoted by means of a'rivet 15 Yto a bracket 16 secured to the vertical'frame vmember 26. The said lever has an offset 11 at its oppositeend and which terminates in an extension 18 projecting through a slot 19 in the end of Vcase A. A knob lisfattached to the projecting end of the said lever. The-levers 6| and 13 are connected together intermediate their ends vby meansof a link 62 which is pivoted to said levers by screws 83 and 84. The levers l52, 53, 6| and 13 all operate in slots 65 formed in the two vertical frame members '25 and 21. The ends of both of the levers 52 andi project outwardly beyond the vertical frame member 21. These ends of said levers have attached to them la tension coil 'spring |03 which has its ends |64 hooked intoholes |5'and |66 in the said levers. The end ||J1of the lever 52 projects outwardly beyond the uprightv 55 'an appreciable amount so that'considerable movement is given to the lever 54 tending to urge'the said lever upwardly and to move the Ybread racks D into non-toasting position.

The timing mechanism E on the invention is of the type disclosed in the patent to R. Sardeson 2,365,909 issued .December 26, 1944. This timing mechanism includes a strip of bimetal 66 which is mounted for reciprocating movement in a guide 81. Guide 81 is attached to an end plate 68 forming part of the framework' B. The end plate 83 has a foot 89 which rests upon and is attached to the iiange 2B of frame member 26 by means Cil of a screw 9|. The upper end of the said end plate is held in proper relation with the vertical frame members 26 by means of a spacer 92. The ends of said spacer are reduced as indicated at 93 and extend through the plate 62 and the vertical frame member 26 and are riveted over as best shown in Fig. 1 to hold the parts attached to one another.

Pivotally mounted ona shaft 94 is a gear segment 95 which is adapted to cooperate with a rack 9U formed on the strip of bimetal 86 by means of spaced openings 96. The shaft 64 is secured to the plate 81. The gear segment 95 has attached to it a section S1 of a ratchet wheel, the teethof'which cooperate with a catch 98. Catch 98 is pivoted on a pintle 99 which is also attached tothe plate 68. The said catch includes a iinger which rests on the bimetal and which is adapted to be raised to disengage the catch 98 from the section 91 of the ratchet wheel and release the gear segment 55, one tooth at a time. A spring |99 Vsecured to the catch 98 and to the plate'f88 urges theingerA ici against the strip of bimetal '86. The bimetal is heated by means of a heater |`62^disposed within lthe guide 81. It will readily becomprehended'that the rate of heating of the bimetal determines the length of time required for the .operationbi the timing mechanism E for eachcooking period.

`The latching device F includesV a -Ushaped arm |98 hereinafter referred 'to as a catch "arm which has spaced flanges "|:59and |.n This arm is pivotally supported onfthe 4spacerV 62 which is in the form of a rod `and which extends through the two flanges |69 and A torsionspring ||2 encircles the spacer 62 between the flanges |69 and I|| and is attached to flange M39 and to the plate 88 to `'cause 'said armto swing normally upwardly as shown in Figs. 3 and 4.

The arm |66 has 'pivoted to the vflange |65 thereof by'means of aT rivet |'|6a depending latch H9. Latch |19 has a catch 12| at the lower end of the same which is formed with-a surface 45 adapted to engage a corresponding surface |46 on a catch engaging-member |22. This catch member formsV part of a bar 'il-23 which is secured to the' gear 'segment 55 by means of rivets |24. Thelatch H9 isv formed with an arcuate slot |25 having depressed ends |26 and |21. In this slot is mounted a pintle |25 which may travel freely `froml one end of the slot'to the other. Thispintle is secured -to a depending link or connector |29 which is censtructed with spaced rfingers i3! and |32 at its lower end. These fingers straddle the lever 6| and when the said-lever is moved downwardly the said-link impart-s tothe latchv l|-i9-downward movement.

A gear segment ||3 is formedon the gearsegment 95 which is adapted to`mesh' with a gear pinion |4. vThis pinion is attached toa shaft ||5 which is journaled in a bearing |16 -mounted on the plate 86. A fly wheel A| I1 is Y"also attached to the shaft vH5 andthe said ily wheel absorbs the energy-produced by the spring H13-'andallows the breadracksD 4to move less rapidly to normal position at the end of the timingperiod.

For resetting the timing device E link |29 is lormed with a shoulder |33. This shoulder is adapted to engage a lug |34 on the bar `|23 'and to rotate the gear segment $5 in a Vdirection opposite to that resulting from theoperation of the timing mechanism E, thus resetting lthe timing mechanism.

In conjunction with 'the lever 6| a switch mechanism yfor energizing and deenergizing the heaters is employed which includes fixed contacts |35 and a movable contact member |36. The contacts |35 are mounted on an insulating support |31 attached to a portion |38 of plate 88.

vThe. contact member 36 is secured to the end of a spring |39 which is also attached to the plate 88 by means of screws |4|. A cam follower |42 secured to the lever 6| engages a cam |43 on the spring |39 and moves the contact member |36 into engagement with the contacts |35.

The parts are normally arranged as shown in Figs. 3 and 4 with the pintle |28 disposed in the end |2`| of slot |25. Downward movement of the lever 6|` causes the latch ||9 to travel downwardly. It will be noted that the slot |25 is exactly below the rivet ||8 serving as the pivot for arm |08. In such position the force is applied to the latch ||9 to the right of the vertical plane passing through the axis of the rivet ||8. This causes the catch |2| to be drawn against the catch engaging member |22. When the said catch passes beneath said member the catch hooks onto the same as shown in Fig. 5. Upon release of the lever 6| the pintle |28 rides along the upper surface of the slot |25 and reaches an intermediate position as shown in Fig. 5. Spring |63 now urges the lever 52 and correspondingly the lever 6| upwardly and said lever through link |29 and catch ||9 energizes the mechanism E. As the timing mechanism operates, gear segment 95 rotates and as it rotates the bar |23 rotates with it until it reaches the position shown in Fig. 7 As the bar |23 rotates,

the angularity of the surface |46 thereof with 5 respect to the direction of movement of the latch ||9 varies and becomes more acute. The friction between the surfaces |45 and |46 hence becomes less and the direction of extent of the surface |46 approaches the direction of movement of the latch ||9 so that the catch |2| rocks on the surface |46 and is released from the catch engaging member |22 without excess force. Upon further movement of the timing mechanism the latch is released and the lever 6| and associated parts move upwardly. The shoulder |33 on link |29 then engages the lug |34 on bar |23 and resets the timing mechanism. It will be noted that the lug |34 is to the right of the slot |25. This causes the pintle |28 to be forced into the end |2'| of slot |25 where it resumes the position shown in Fig. 4. The latch ||9 is now reset to again repeat its cycle.

If during the toasting period it becomes desirable to manually release the bread racks, the same can be accomplished by depressing the lever 6| a second time. The position of the parts during toasting is shown in Fig. 5. Downward pressure `on the iinger |32 causes the pintle |28 to travel to the end |26 of the slot |25 as shown in Fig. 6. This applies force to the latch ||9 in a direction forcing the catch |2| out of engagement with the lug |22. Upon release of the lever the bread racks are returned to normal position through the action of the spring |03.

The advantages of the invention are manifest. The force used in operating the timing device is also used to eiect release of the latching means thus eliminating two forces acting in opposition to one another as is the case with certain other types of bread toasters. By means of the structure of the instant invention less force is used in initiating operation of the toaster. With my invention friction is reduced at the time of release .between the catch and catch engaging means so that release is accomplished with a minimum expenditure of energy and the sticking of the parts and failure of operation prevented.

Changes in the specific form of my invention, as herein described, may be made within the scope of what is claimed without departing from the spirit of my invention.

Having described my invention, what I claim as new and desire to protect by Letters Patent is:
